About the solution
The G4B’s technology is based on echolocation (when the sound waves hit a nearby object, they produce an echo that bounces back). It works by using ultrasound and infrared sensors that can help blind users detect obstacles on their path. It can detect any obstacles on all sides within a distance of two meters. The infrared sensor located in the middle of the device allows it to detect obstacles in case the ultrasound sensors fail.
Every time the gadget finds an obstacle, a beep sound is heard (through the audio output) along with vibration, to alert the user.
“The idea (for G4B) struck when a blind woman asked me for directions, which made me think how difficult it might be to the blind in today’s world where the streets are crowded and cluttered with electric poles, signboards etc.”, Anang explained.
The student always loved tinkering and learned things by himself. “I spend most of my time making new things, maybe a robot, gadget. Science, especially physics, has always been my interest area and since we didn’t have television, mobiles or internet, I learnt by opening remote-controlled cars, broken gadgets etc.”, he said.
Up to 2017, Anang had created three prototypes, which he showcased to the world. As soon as the final prototype is read, the inventor will he aided by UNICEF, among others, in promoting it and getting the G4B to the market.
The inventor already won several awards, which have been a valuable resource for him to be able to develop his projects.
“You will know how I work if you were with me – I go without sleep for 2-3 days at a stretch when I start working on something, because if I don’t win the first place in a competition, I will fall short of money for my next project”, Anang noted.
The young man wants to keep working as an inventor. “I want to make the world a better place to live in. My passion for ideas, innovation and inquisitiveness about how machines work will forever persist. And I will continue to create”, he expressed.
